摘要
The title zinc(II) complex salt [Zn(H2O)(6)](ClO4)(2)center dot(PNOS)(4), where PNOS is derived from picolinaldehyde N-oxide with semicarbazone, has been prepared and structurally characterized by X-ray single-crystal analysis. It crystallizes in triclinic, space group P (1) over bar with a = 7.529(3), b = 10.206(4), c = 14.678(6) angstrom, alpha = 86.293(6), beta = 87.686(7), gamma = 81.382(6)degrees, C28H44Cl2N16O22Zn, M-r = 1093.06, V = 1112.3(8) angstrom(3), Z = 1, D-c = 1.632 g/cm(3), S = 1.089, mu(MoK alpha) = 0.773 mm(-1), F(000) = 564, the final R = 0.0438 and wR = 0.1076 for 3888 independent reflections with R-int = 0.0224. The crystal structure possesses a [Zn(H2O)(6)](2+) cation, two ClO4- anions and four PNOSs. In the crystal structure, Zn2+ cation is located at the symcenter and coordinated by six water molecules. In [Zn(H2O)(6)](2+), an elongate octahedral complex cation, the average Zn-O bond length is 2.087(2) angstrom. There exist a lot of H bonds in the structure, linking the cation [Zn(H2O)(6)](2+), anion ClO4- and PNOS to form a 3D network.
